Abstract

PURPOSE:To uniformize temperature distribution and improve the comfortable property of a living space employing an air-conditioning machine, upon starting the cooling operation thereof by cooling a human body directly in the initial period of the operation, thereafter, cooling the wall surfaces of the like of a room. CONSTITUTION:The title air-conditioning machine maximizes the flow amount of a fan 16 upon starting the cooling operation thereof while driving an airflow direction deflecting van 1 downward and the deflecting vanes 5a, 5b rightward and leftward. In this case, the blow-off air of the machine is concentrated downward and is collided against a human body directly. When time has elapsed to some degree, the deflecting vanes 5a, 5b are deflected oppositely and the circumference of the human body as well as the wall surfaces of a room are cooled by the downward distributed blow-off air. When the time of operation has elapsed further, the deflecting vane 1 is driven upward and the flow amount of the fan is minimized. In this case, the blow-off air is distributed horizontally and comfortable cooling effect may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction deflection device for controlling the blowing direction of an air conditioner.

BACKGROUND OF THE INVENTION Until now, various devices have been devised as wind deflection devices for air conditioners in order to improve the comfort of living spaces.

For example, there is a device that swings the upper and lower deflection blades at a constant period. (Japanese Patent Publication No. 56-21149) Problems to be Solved by the Invention However, the above conventional configuration can only control the deflection in the vertical direction, and the left and right changes must be done manually, so
Only air conditioning was available. Another problem was that the temperature distribution in the room deteriorated. Furthermore, since the air swings from the start of operation, there is a problem in that the cold air does not hit the human body when the air conditioner cools down, making it impossible to obtain a sufficient cooling effect.

An object of the present invention is to improve the comfort of a living space using an air conditioner, particularly to improve the comfort at the start of cooling operation.

Means for Solving the Problems In order to solve the main problems, the present invention compresses the refrigerant,
An indoor unit that includes a compressor that constitutes a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger, a variable air volume blower, and the indoor heat exchanger; An air outlet that blows out the air that has passed through the air outlet; a vertical deflection blade that deflects the air that is blown out from the air outlet in the vertical direction; Left and right deflection blades that branch and deflect in directions, drive means that deflect and drive the upper and lower deflection blades and the left and right deflection blades independently, a rotation speed variable means that controls the air volume of the blower, and an air conditioner, elapsed time detection means for detecting elapsed time from the time when a certain operation is performed; set time storage means for memorizing a preset time; and said upper and lower deflection blades through which air is directed downward and concentrated from said air outlet. and that the elapsed time detected by the elapsed time detection means has reached the first elapsed time stored in the set time storage means when the left and right deflection blades are in the state and the variable air volume blower is at the maximum air volume. Detected, the vertical change blade maintains the above state, the left and right change blade is rotated from a concentrated position to a position where it branches left and right, and the air volume of the variable air volume blower is set to medium, and the air volume is adjusted to the above setting. From the start of operation,
Detecting that a second elapsed time has come, and driving the signal to rotate the vertical deflection blade from a downward direction to a horizontal or upward position to minimize the air volume of the variable air volume blower. and means for generating a signal to be applied to the rotation speed variable means.

Effect With the above configuration, the air deflection device of the air conditioner of the present invention has a maximum air volume and concentrates downward when the air temperature is high, such as when starting cooling operation, so the cold air directly hits the human body, resulting in a rapid cooling down effect. is obtained. In addition, if the temperature of the air outlet drops to a certain extent after a certain period of time after the start of operation, it will cause discomfort if the cold air is applied directly to the human body.

When the temperature of the living space is sufficiently low, the air volume is diverted downward inside the room, so that cooling can be performed to wrap around the lower part of the room near the living space without directly applying cold air, resulting in an improved experience. When the above-mentioned movement time passes, that is, when the blowout temperature falls, the air volume is minimized by horizontal division, so air flows from the top to the bottom of the room without direct cold air, creating a cooling effect that is close to natural. can be obtained, and power consumption can be reduced.

Embodiment Hereinafter, a wind direction deflection device for an air conditioner according to an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is an exploded perspective view of essential parts of the device.

As shown in the figure, it is slightly curved in the direction of the balloon,
A vertical deflection blade 1 that performs vertical wind direction deflection by the Coanda effect has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to an intermediate motor (stepping motor) 3. The left and right deflection vanes that horizontally deflect the blown air by the Coanda effect are composed of a left deflection vane 5a connected to a coupler 4a and a right deflection vane 5b connected to a coupler 4b. And the left deflection blade 5a is
Feather lever arm 6a, Ron door a.

It is connected to a left motor (stepping motor) 9a via a motor lever arm 8a, and the right deflection blade 5b is connected to a blade lever arm 6b and a rod 7b.

It is connected to a right motor (stepping motor) 9b via a motor lever arm 8b. Here, left deflection blade 5
a is slightly curved so that its center is to the left of this left deflection blade 5a, and right deflection blade 5b is slightly curved so that its center is to the right of this right deflection blade 5b. That is, both sides 13a of the air outlet 12, which will be described later,
13b to cause the aforementioned Coanda phenomenon and deflect the wind direction. Since the Coanda effect is a well-known technique, its explanation will be omitted.

In this embodiment, the middle motor 3. Left motor 9a.

Although the right motor 9b constitutes the driving means, it is also possible to use a single motor for driving the left and right deflection blades, and furthermore, by using a switching means such as a gear or a clutch, the upper and lower deflection blades 1 and the left and right deflection blades can be switched. It is also possible to control the motor with a single motor.

In addition, the motor is not limited to a stepping motor, but an induction electric α
etc.

In addition, the reason why the left and right deflection blades are divided into two parts, the left deflection blade 5a and the right deflection blade 5b, is to facilitate the concentration and separation operations that are the object of the present invention, and also to be able to independently control the wind direction. In order to perform more delicate control of the wind direction, the structure may be further divided into smaller sections, or conversely, the structure may be connected by a single coupling device 4 as shown in FIG. 2 without being divided. Also, the reason why the left deflection blade 5a and the right deflection blade 5b are curved is as follows.
In addition to deflecting the wind direction by the Coanda effect, the shape is to enhance the concentrated one-split flow effect that is the object of the present invention, and if the Coanda effect is not taken into account, it may be a flat shape that is not curved. The reading direction may be reversed.

Next, FIG. 3 shows a perspective view of the indoor unit 10 to which the wind direction deflection device shown in FIG. 1 is installed.

In the figure, an indoor unit 10 has a suction port 11 on the front surface for sucking indoor air, and below the suction port 11 are vertical deflection blades 1 and left and right deflection blades 5a.

An air outlet 12 having a diameter 5b is provided. Both sides 13a and 13b of the Suita mouth 120 are respectively curved surfaces that gradually expand outward in order to control the wind direction by the Coanda effect as described above. Further, as described above, the lower surface portion 14 is also a curved surface that gradually expands in order to deflect the wind direction by the Coanda effect. A side sectional view of this indoor unit 10 is shown in FIG. An indoor heat exchanger 15 is installed at a position facing the suction port 11.
A blower 16 is provided in the ventilation path from the indoor heat exchanger 15 to the air outlet 12.

Next, FIG. 5 shows the refrigeration cycle of this embodiment.

In the figure, compressor 17. Four-way valve 18. Indoor heat exchanger 15. Capillary tube 19. Outdoor heat exchangers 20 are connected in a ring. Here, during heating operation, the refrigerant is
Compressor 17. Four-way valve 18° indoor heat exchanger 15. Capillary Yupe19. It flows in the order of the outdoor heat exchanger 20, and during cooling operation, the compressor 17. Four-way valve 18. Outdoor heat exchanger 20
．． Capillary tube 19. The heat flows through the indoor heat exchanger 15 in this order.

Here, a circuit diagram of the main part of this embodiment is shown in FIG.

Inside the microcomputer 22, a storage section 23.0 stores a preset time. A signal generating means 24 generates an appropriate output signal by comparing the set value stored in the storage section 23 with an input value, and the rotation speed of the variable air volume blower 16 is changed by the signal generated by the signal generating means 24. It has rotation speed variable means 25. On the input side of this microcomputer, there is a timer 2 which is a time detection means.
1, and on the output side, each motor 3, 9a, 9b and a variable air volume blower 16. The middle motor a and the left motor 9a, which are driving means, are connected via a buffer 27 that supplies pulse output to the
, right motor 9b, variable air volume blower 16. is connected. 29 is a timer coil.

Now, to explain the relationship between the block diagram shown in FIG. 11 and the circuit shown in FIG. 6, the timer 21 in FIG. 6 corresponds to the time detection means in FIG.
The signal generation means 24 in FIG. 6 corresponds to the signal generation means in FIG. 11, and the rotation speed variable means 25 in FIG. 6 corresponds to the rotation speed variable means in FIG. Correspondingly, each motor 3, 9a, 9b in FIG. 6 corresponds to the driving means in FIG. 11.

Next, the operation of this embodiment is shown in FIG. This figure is a flowchart during cooling operation.

The operating time is the time detected by the timer 21 and is 5t1.
t2 is a set time. When this operating time t is less than the first set time t1, the middle motor 3 is rotated to the left, and the left motor 9 is rotated to the left.
Rotate the motor a counterclockwise, rotate the right motor 9b clockwise, and then stop to maximize the air volume of the variable air volume blower. Here, rotating the middle motor 3 to the left moves the vertical deflection blade 1 to the lower position, rotating the left motor 9a to the left moves the left deflection blade S& to the right, and rotating the right motor 9b to the right moves the right deflection blade 1 to the lower position. 5b
indicates that it is driven to the left. That is, the blown air is concentrated downward, as shown in FIG. 10. At this time, the upper and lower deflection blades 1. Although it is not known what initial state the left deflection blade 5a and right deflection blade 5b are in,
After each motor 3.9a, 9b is driven, it always rotates to the position described above. That is, when the deflection is already at the same position as the position after driving in the initial state, the motor is prevented from rotating by a load resistance such as a stopper, or the motor is allowed to rotate idly.

After each motor 3, 9a, 9b has rotated (before or during rotation as required), the time set in the timer 21 and the set time are again compared.

Next, if the time t of the timer 21 is longer than the first set time and less than the second set time 12, the middle motor 3 is rotated to the left, the left motor 9a is rotated to the right, and the right motor 9b is rotated to the left. Stop. Also, set the air volume to medium. In other words, the blown air becomes a downward branch.

The result is as shown in FIG. When the left and right deflecting blades 5a are already concentrated downward in FIG. 10 before this operation, the left and right deflecting blades 5a are
, 5b are deflected.

Next, when the timer 21 reaches the second set time 12 or more, the middle motor 3 is rotated to the right, the left motor 9a is rotated to the right, and the right motor 9b is rotated to the left, and the air volume is minimized. . That is, the blown air becomes horizontally divided as shown in FIG.

By performing the above operation, when the temperature of the air outlet is high, such as at the start of operation, the air volume is maximized and concentrated downward, as if directing cold air to the human body, and after a certain amount of time has passed and the temperature of the air outlet has cooled down, the airflow is concentrated downwards. The air flow is divided downward to cool the human body.

When the operating time has passed sufficiently and the blowout temperature is low enough, the air flow becomes horizontally divided to the minimum to cool the entire room.

The effect of such an operation at the start of cooling operation will be explained. First, since the air temperature at the start of cooling operation is high, unless the air is applied directly to the human body and the air volume is maximized, it will take too long for the air to cool down. Therefore, it is preferable to apply wind directly to the human body. In other words, by directing the airflow to a downwardly concentrated manner with maximum airflow, an air-conditioning effect that can cool the human body more quickly is achieved.

Next, when a certain amount of time passes and the temperature of the air outlet becomes low, the air volume is diverted downward, so that cooling can be performed in a way that envelops the lower part of the room near the living space. That is, by cooling the area around the human body and also cooling the wall surface, the temperature distribution within the living space can be made uniform.

When the operating time further elapses and the blowout temperature becomes lower, the air flow becomes horizontally divided with the minimum amount, so a sufficient cooling effect can be obtained without directly blowing cold air to the human body. That is, in the initial stage, the human body is directly cooled, and the walls and the like are later cooled, so that the temperature distribution is uniform, and there are no local hot spots in the living space. Also, power consumption is reduced.

Effects of the Invention As is clear from the description of the above embodiments, when the time from the start of operation is shorter than a certain set time, the air volume is concentrated downwards at its maximum, so the air is directed directly onto a person's body to enhance the sensory effect. A faster falling effect can be obtained.

Next, when the above operating time reaches a certain set time, the air flow is diverted downward to make the temperature distribution in the living space uniform in order to cool the wall surface without impairing the bodily sensation.

When the driving continued and the second set time came.

This creates a horizontally divided flow with the minimum amount of airflow, making the temperature distribution even more uniform, eliminating local hot spots, and at the same time providing a comfortable cooling effect by blowing cold air from above. Furthermore, since the air volume is reduced, power consumption can be reduced by the amount of input to the blower.
